Charlemagne sent who out to catch dishonest officials?

Charlemagne sent officials known as "missi dominici," or "envoys of the lord," to catch dishonest officials in his empire. These envoys were tasked with monitoring local rulers and ensuring that justice was upheld, particularly in the collection of taxes and the administration of laws. They traveled in pairs, typically one cleric and one noble, to maintain oversight and report back on the conduct of local authorities. Their role was crucial in maintaining the integrity of Charlemagne's administration and reinforcing royal authority across his vast territories.
